400 stroker rookie

I don't think the FI will like the long duration of that cam, it should probably have more like 112 or 114 LSA for nitrous and FI.

If you already have the maincaps and girdle, using it won't hurt anything, and could help. I use aluminum caps on my engines, I think it's cheap insurance. S/F...Ken M
